PLATFORM SUPPORT.

Application filed November 8, 1924. Serial No. 748,743.

This invention relates to collapsible tripodal'platform supports fortables, platforms, and the like and has for its objectto improve andcheapen the construction thereof. 7

Fig. 1 is a side elevation illustrating two of the supports embodyingthe invention and the manner of using them to support a table top.

Fig. 2 is an end elevation of the support.

Fig. 3 illustrates a modified manner of using two of the supports inconjunction.

Fig. 4 is a plan view of the support.

Fig. 5 is an end elevation of the support in collapsed condition.

Fig. 6 is a plan view of Fig. 5.

Fig. 7 is a detail illustrating the manner of pivotally connecting thethird leg to the support.

As here shown, the collapsible tripodal platform support embodying theinvention includes the three straight supporting legs- 10, 12 and 14which, when the support is spread into supporting condition, divergeoutwardly and downwardly whereby to provide a stable bearing on thefloor or other supporting surface.

Two of said legs, as the legs 10 and 12, are permanently connectedrigidly together at their upper ends by the bar 16 and brace 18 to bedisposed, when in use, in an approximately vertical plane. Said bar 16is secured to the upper ends of said legs 10 and 12, and oncorresponding side faces thereof, by suitable means-as screws 20; andsaid bar extends on opposite sides of said legs for a substantialdistance whereby to provide a stable bearing for a table top a orequivalent. Said brace 18 is disposed in spaced relation below said bar16, and parallel therewith, and is permanently secured rigidly to saidlegs 10 and 12 by suitable means as screws 22, and on the same sidefaces thereof to which said bar is attached. The third leg 14 isprovided with a. platform-supporting bracket hereinafter to bedescribed, and said leg with its bracket is pivotally connected with theother two legs in such a manner that it can be swung about its pivotalconnectioninto an approximately parallel relation with said legs, inwhich collapsed condition the support will occupy but little space andcan be stacked and transported readily. Said leg and bracket can be alsoswung into an expanded position at right angles with said other legs, inwhich position the support is in condition for service.

The pivotal connection for said third leg includes a board 24 ofsubstantial thickness dis osed in the space between said her 16 brace 18and adapted to engage loosely with said bar and brace. Theupper end ofsaid leg 14 is fixed to said board, on one face thereof, by suitablemeans as screws 26. Said board is pivotally connected with said her 16and brace 18 by the pivot pins 28 and 30, which pins are looselyreceived in aligned holes in the upper and lower edges of said board;and in the proximate faces of said bar and brace, as is illustrated moreclearly In Fig. 7. The upper end of said third leg 14 preferably isextended upwardly above said board and is formed or provided witha'beveled face 32 which is adapted to engage with the side face of thebar 16, in the open position of the support, whereby to hold said leg,in one direction, in proper relation with the fixed legs. \Vhen the legand board are swung about their pivotal connection, in the oppositedirection, to a fully collapsed condition of the support, the board isadapted to lie between the bar 16 and brace 18 and the leg 14 is adaptedapproximately to overlie one of the fixed legs, or the leg 10, asillustrated in Fig. 5.

Said pivoted third leg is provided with a table supporting bracketcomprising afibar 34, which bar is fixed to said board 24, on the sameside with said leg, and is extended approximately at right anglesupwardly and outwardly from said leg; and the upper and bevelled end 36thereof is terminated a proximately inthe horizontal plane of t e upperface of said bar 16. As thus arran ed, said bar and bracket cooperate toprovi e a triangular support for a table or platform resting thereon.WVhen a long table-board is adapted to be supported, at least twosupports will be used, one at each end of the board, as illustrated inFig.1. The third leg 14 prevents the support from tilting in thedirection of the third leg and the weight of the table-board on thebracket 34 prevents the support from tilting in the opposite direction.I I

The connections between the legs of the support are all at the upper endthereof, so that there is a clear and unobstructed space, or foot room,between the legs under the connections; and the legs are edgcwisearranged, whereby further to reduce interference with a person seatedatthe table adjacent a support thereof.

WVhen a short table board is to be supported, as the board I), Fig. 3,two supports may be employed and placed with their fixed legs 10 and 12in approximate alignment, as illustrated, whereby to form, in effect,afourlegged support.

I claim:

1. A new article of manufacture comprising a collapsible tripodalplatform support having three triangularly inclined legs, means disposedat the top-portion of the support fixedly connecting two of said legsand including a platform-supporting bar fixed to the upper ends of saidtwo legs and extended in both directions beyond the upper ends ofsaid'legs, means also disposed at the top-portion of the supportpivotally connecting said third leg to said fixed legs, and aplatform-supporting bracket fixed to said third leg intermediate itsends and extended outwardly and upwardly therefrom and terminatedapproximately in horizontal alignment with the upper face of said bar,said support having an unobstructed space between its legs at the bottomportion thereof.

2. A new article of manufacture comprising a collapsible tripodalplatform support having three downwardly and outwardly inclined legs, abar secured to the upper ends and on similar sides of two of said legsand extended in both directions beyond the upper ends of said legs, abrace disposed in spaced relation with and immediately below said barand secured to the same faces of said legs, a board disposed betweensaid bar and brace and adapted to bear against the proximate faces ofboth, means vertically pivotally connecting said board with said bar andbrace, a platformsupporting bracket fixed to the free end of said boardand extended upwardly thereabove and terminated approximately inhorizontal alignment with the upper face of said bar, and meansconnecting the upper end of said third leg rigidly with said pivotalboard, said support having an unobstructed space between its legs at thebottom portion thereof.

3. A new article of manufacture comprising a collapsible tripodalplatform support having three triangularly-inclined legs, a bar securedto the upper ends and on similar sides of two of said legs and extendedin both directions beyond the upper ends of said legs, a brace disposedin spaced relation with and immediately below said bar and secured tothe same faces of said legs,
